Application filed Augnstz, 1916. Serial No. 112,760.

To all whom it may concern:

Be it known that 1, WILLIAM A. P. MON- oonn, a citizen of the United States, residing at Batesville, in the county of Albemarle and State of Virginia, have invented certain new and useful Improvements in Molds for Concrete Structures, of which the following is a specification.

This invention relates to the formation of monolithic or poured concrete buildings and particularly to the molds forconstructing said buildings.

One object of this invention is to provide a mold of this character having very few I parts and these of a very simple character so that the weight of the mold sections for any ordinary structure will be relatively small and permit the mold to be readily transport ed by truck from one location to another.

A further object is to provide a mold structure which may be readily set up, readily taken down without the use of skilled labor and which will be very effective in use.

A still further object is to provide mold sections which may be readily detached after the concrete is set, and in this connection to provide mold sections whose contours are such that an eaves or cornice may be formed around the building with a depending fillet or other depending portion and provide means whereby the mold sections may be allowed to drop after the concrete has set, to thereby release the mold sections from these depending portions of the concrete struc ture and permit the withdrawal of the sections. 1

A further object is to provide a supporting frame of skeletonic character with which the mold sections are detachably engaged and by which they are held in position, and in this connection to provide a mold section having lapped and interlocking joints capable of ready disengagement from each other.

Still another object is to provide for the formation of window sills or like parts and particularly to provide for the escape of air from the space beneath the*' window sill molds so that the liquid or semi-liquid concrete when it is poured may fill up the space beneath these window sill mold sections without the inclusion of air.

Still another object is to provide for the application of panels of a more or less ornamental character to the side walls of the mold structure and provide for the detachment of these panels from the mold sections so that the mold sections may be removed, leaving the panels in place and then the panels may be removed later.

Other objects will appear in the course of the following description.

, My invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a side elevation of my mold in operative position;

Fig. 2 is an end elevation of the same;

Fig. 3 is a vertical section through one side of the mold structure showing the braces in elevation;

Fig. 8 is a vertical sectional view on the line 8-8 of Fig. 7;

Fig. 9 is a perspective view of the construction shown in Figs. 7 and 8;

Fig. 10 is a fragmentary perspective view of two conjoined mold plates;

Fig. 11 is a transverse sectional view of the same; and

Fig. 12 is an enlarged vertical section on the line 1212 of Fig. 1.

My improved mold is composed of a skeletonic structure comprising a plurality of vertical outer channel beams or upright framing members 10 and inner upright framing members 10*, to which are detachably connected three sets of outer horizontal rectangular frames of channel iron, these frames being designated generally 11, 12 and 13, and three inner frames designated generally 11*, 12 and 13. Each of the outer frames is composed of the side bars 14 and the end bars 15. These end bars extend beyond the ends of the side bars and are pro vided with angularly projecting tenons 16. Each tenon 16 passes through a slot in a corresponding angle iron 17 attached to the adjacent end of the lateral beams 14. VVedg- T' ing keys 18 are driven through these slotted tenons and thus the parts are locked to each other. Each of the inner frames is likewise composed of side bars 14 and end bars 15, and the side bars are connected to the end'bars by angle members 16 and in turn connected to the end and side bars by tenons and wedges as illustrated in Fig. 4.

The middle rectangular frames 12 and 12 are supported upon the uprights 1'0 and 10 by transverse braces 19 which are disposed to extend through the window openings of the completed building. These braces extend through apertures 20 in the beams 14 of the frame 12 and through apertures 20 in the beams 14 of the frame 12 and also through apertures 21 in the vertical beams 10 and 10*, the ends of these braces are formed with slots 22 forthe reception of Wedges 23. Thus the middle frames 12 and 12" are connected to the supports 10 and 10*, braced from each other and sustained.

The upper and lower frames 11 and 11 and 13 and 13 may also be connected to each other and to the beams 10 and 10 by tenons and keys, but in this case the tenons 24 extend outward from the beams let and and are not formed as braces extending transversely across the space between the mold sections. The keys 23 hold the frame beams in engagement in the manner heretofore described.

The mold proper is composed of a plurality of vertically disposed outer sheet metal mold sections 25 and a plurality of vertically disposed inner sheet metal mold sections 25*. These mold sections have any convenient width and any desired height depending upon the building to be constructed and upon the weight of the mold sections, it being desirable that a mold section shall be relatively light. The upper ends of the outer sections are outwardly and then upwardly extended as at 26 to constitute a mold for an overhanging cornice, said co-rnice mold having a depending bead or fillet 27. The mold sections 25 may be formed at their upper ends to extendinward and upward and engage with adjacent mold sections 28 to form a mold for a roof, if a concrete roof is desired as will be hereinafter explained. However, the mold as designed is adapted to be used for the construction of ahouse' having walls of concrete with a wooden roof or roof frame.

One vertical edge of each mold section is offset as at 29 to provide a deflected seat for the adjacent fiat margin of a next adjacent mold section as illustrated in Fig. 10. A lap joint is thus provided and to lock these adjacent margins of-the mold section to gether and to the beams 14 and 14 of the outer and inner frames 11 and 11 12 and 12 and 13 and 13, the'flat margin of one mold section is formed with an outwardly projecting tenon 30 which passes through the deflected portion 29 and through the wedges of the horizontal beams 14 and let,

these tenons being slotted for the reception of key wedges 31. The upwardly and inwardly curved portions of the inner mold sections 25 may also have a lap joint with the mold sections 28, this joint being designated 32 and the mold sections being held in engagement with each other by a tenon 33 and a wedge 34.

In order to support the mold sections in a raised position, that is the position shown ir Fig. 3, relative to the lower faces of the beams forming the frames 13 and 13, these beams are formed on their inner faces with abutments equal in thickness to the thickness of two mold sections, and when in operative position, the mold sections rest upon these abutmcnts. lVhen the beams forming the lower frames 13 and 13" are removed however, after the concrete has set, the supporting abutments 35 are also removed. from beneath the lower ends of the mold sections and the mold sections therefore drop to an extent equal to the height of the abutments 35. This height is at least equal to any downwardly projecting portions of the eaves or of the window lintels. Thus by removing the beams of the lower frames 13 and 13 the sheet metal mold sections will drop downward so that the beads 27 will escape the fillet molded by the head on the cornice so as to permit the ready removal of the mold sections when the remainder of the frame is taken away. The apertures through the deflected portions 29 of the mold sections, which apertures are. designed for the passage of the tenons 30 are vertically lengthened or have the form of slots to permit the descent of the sections independently of each other.

Certain of the mold sections which are designated 25 and 25- are cut out as at 35 to provide for window openings and the margins of these openings are inwardly turned so as to mold the jambs of the window opening, the lintel and the sill. The

lateral inturned edges or margins of these mold sections are designated 36. wardly turned margins which form the lintel of the window are designated 37. A special construction has to be provided for those inwardly turned margins of the opening 35 which form the sill of the window. As illustrated in Fig. 5, the portions of the mold sections which are to form the window sill are bent inwardly and upward as at 37 and 38 and the window frame 39 may be put in place between these sections. The in wardly' turned portions 37 and 38 are formed each with a longitudinal opening .10 and this opening is normally closed by a hinged section 41, which, when closed comes fiushwith the under face of the inwardly turned portions 37 or 38. Now when the concrete is being poured it rises upward in The inthe space beneath the window opening and if the portions 37 and 38 were solid, air would gather in the upper portion of the mold space beneath the window sill and the concrete would not properly fill the space up to the portions 37 and 38. By opening the end sections 11 however, this air is allowed to escape and the concrete therefore rises up freely and then when it has nearly filled the space beneath the window sill, these sections 11 are closed, and more concrete is poured in until the space between the window sill molds is fully filled.

In order to provide for the formation of ornamental depressed panels in the concrete walls of the structure, I provide panel molds designated generally 42, these panel molds being attached to the mold sections 25, or 25 by means of screws 25 which are removable from the exterior of the mold sections. After the concrete has been poured into the mold and has set so that the mold may be removed, the frame work of the structure is removed, then the screws holding the panels 4-2 to the mold sections are removed and then the mold sections taken off, leaving the panel molds 42 in place set into the concrete. These may be readily removed later. It is of course obvious that these panel sections may have an ornamental character and various forms.

The practical use of my invention will be obvious from what has been stated. A foundation A of concrete is first made, the face of this foundation being approximately level with the ground, the beams 10 and 10 are then erected and the frames 11 and 11 12 and 12 and '13 and 13 are connected to these uprights, the braces 19 holding the frames in proper spaced relation. The mold sections are then put in place and engaged with the horizontal beams and with each other as was previously described. If the structure is to have a concrete roof, the mold sections 28 are put in place. If it is not to have a concrete roof however, these mold sections are left off. The nearly fluid concrete is then poured into the space between the mold sections until it rises up to the cornice, suitable means provided for causing the formation of a gutter in the face of the roof and if a wooden roof is to made, a beam B, shown in dotted lines in Fig. 3, is set in the concrete to which the rafters of the roof are adapted to be attached. If, however, the roof is to be of concrete, no such beam is used. After the concrete has hardened, the beams of the lowest frames 13 and 13 are released from engagement with the mold sections and this, because they carry the abutments 35, permits the mold sections to drop downward so as to disengage their upper ends from the cornice or ceiling of the structure. The several vertical beams may then be removed and the horizontal beams removedby disengaging the braces 19 and then the mold sections may be shifted outward one by one until they are entirely removed from the completed structure.

It will be seen that this mold is very easily set up and as easily taken down. It does not require skilled labor, as all the parts are engaged with each other in practically the same manner by tenons and wedging keys. By the use of the wedging keys it is possible to cause the parts to be brought in tight engagement with each other and lock the parts securely in their operative position. The beams and mold sections may be made of very light material and may be readily transported from one location to another. I have designed this molding structure for particular use in building small houses, out buildings and garages, but it is obvious that it may be adapted for building other structures. As designed, the mold sections, beams, etc., of the structure for a garage barn or other like building may be readily transported in a single truck and the several parts may be readily handled by one or twomen.

In order that the sections 25 and 25 shall be readily removable, it is preferable to form each of them in two sections so that .the lower section can drop down with the remaining mold sections 25 and .25 when the lower beams 13 and 13 are removed. The upper half of each of the mold sections 25 and 25 may be supported in proper position by means of the pins 13 shown in Fig. 1. The inwardly extending flanges 14:, which define the door opening, as illustrated in Fig. 2 are preferably formed orattached to the inner faces of the mold sections 25*.
